Answer :
There is no effect on earth's orbit due to similar force of gravity of black hole.
How would Earth's orbit change?
If our Sun was replaced with a black hole having the same mass, Earth's orbit will not changed because of the same force of gravitation of balck hole on earth. Due to this replacement, Earth's temperature will change because balck hole is not too hot like sun.
So we can conclude that there is no effect on earth's orbit due to similar force of gravity of black hole.
